The Motley Fool's CAPS investing service is one of the newest additions to the investing community at Fool.com, and it's another great way for investors to work together to beat the market. One of the features in CAPS allows users to set up a blog to talk about their picks, investing strategy, market view, or their favorite football team (if they so desire).

I've scoured through the CAPS blog universe to bring you a generous helping of the top blog posts for the past week.

Did Wall Street value builders incorrectly?
The housing debate continues! With the release of Lennar's (NYSE:LEN) third-quarter earnings, we all got to see that the numbers for the homebuilders are going nowhere but down. I mean, they were just ... ouch!

The stock prices of homebuilders such as Hovnanian (NYSE:HOV), Lennar, and KB Home (NYSE:KBH) continue to decline from already beaten-down prices, making me wonder how one could even value these falling knives. In a blog post this week, CAPS player floridabuilder -- after bashing Wall Street a bit for getting it all wrong -- gives his take on how investors should be running the numbers on homebuilder stocks.

Median home prices rise for the first time
While floridabuilder remains ardently against homebuilder stocks, fellow CAPS player EScroogeJr holds an entirely opposite opinion. EScrooge looks at a recent release from the NAR, which showed that the median home price nationally rose 0.2% -- deathly slow, but better than a decline. He argues that this price uptick suggests that some bears' doomsday scenarios are overstated.

CAPSCenter
CAPSCenter offers some great stock-picking TV this week, starting with a look at an All-Star's pick of networking giant Cisco (NASDAQ:CSCO). If you're ready for more after that, check out the 2007 Fantasy FoolBall draft. If you ask me, there's nothing quite like picking stocks on a cool autumn Sunday!

In praise of investment clubs
Wow! In a blog post on Tuesday, CAPS player StockSpreadsheet gave an unbelievable rundown of investment clubs, and why he thinks they're worth your while. This is a really thorough piece, and I highly recommend it to anyone who's just getting into investing and has never heard of investment clubs. I'd also recommend it to more seasoned investors who're looking to get the creative juices flowing with some other investors. Ahh, what the heck -- I recommend that everyone read this.

Recommended reading
If there's one thing I love more than investing, it's reading books about investing. In a recent blog post, themattgrdt (don't ask me how to pronounce that ...) provides a great reading list for anyone who's serious about investing. And of course, the fact that the list's top book is Ben Graham's The Intelligent Investor just makes me love it all the more.

Why you shouldn't buy into the upcoming Classmates.com IPO
If you haven't heard yet, Internet access and media company United Online (NASDAQ:UNTD) is getting ready to spin off its social-networking subsidiary, Classmates.com. Yup, you heard me right, social networking. As hot as that trend may be, not everyone is convinced that Classmates will be a good deal. In his recent blog post, Lance912 tells you why you should skip this IPO.

Eldrehad's September 2007 pick
I sure hope that everyone made it down this far, since I've saved the best for last. Continuing his new CAPS newsletter venture, TMFEldrehad (aka EldrehadsPicks for the newsletter), one of the elitest of elite players in CAPS, shares with readers why they should consider picking up shares of Flowers Foods (NYSE:FLO).

So now it's your turn -- get off the sidelines, join CAPS, and start up your own CAPS blog to share your own knowledge and insights with the rest of the CAPS universe.
